Impressively, Amazon shows up on the list twice: once for the company as a whole, and again for its Kindle brand of e-readers and tablets.

YouGov BrandIndex measures consumer perception on a daily basis. The firm interviews 5,000 people each weekday from a representative US population sample, resulting in more than 1.2 million interviews per year.

All brands were measured using the firm's "Buzz" score, which asks respondents: "If you've heard anything about the brand in the last two weeks, through advertising, news or word of mouth, was it positive or negative?"

Brand scores range from 100 to -100 and are compiled by subtracting negative feedback from positive. For example, a score of zero means that the brand received an equal amount of positive and negative feedback.
